Question

I have:

String query = "INSERT INTO Basestations VALUES(?, ?, ?, ?, ?, ?, ?,"
               + "?, ?, ?, ?, ?, ?, ?, ?)";                  


PreparedStatement prep = conn.prepareStatement(query);

prep.setInt(1, profile.getNetworkId());
prep.setInt(2, profile.getBaseStationId());
prep.setInt(8, profile.getLoadLevel());
prep.setInt(11, profile.getPositionX());
prep.setInt(12, profile.getPositionY());
prep.setInt(13, profile.getPort());

prep.setDouble(3, profile.getSignalStrength());
prep.setDouble(4, profile.getFrequency());
prep.setDouble(6, profile.getMaxBitrate());
prep.setDouble(7, profile.getGuaranteedBitrate());
prep.setDouble(10, profile.getRange());

prep.setString(5, profile.getNetworkType());
prep.setString(9, profile.getProvider());
prep.setString(14, profile.getCharging());

prep.setBoolean(15, true);


prep.executeUpdate(query);

and i am getting:

INFO: SQL Exception:
INFO: State : 42000
INFO: Message: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)’ at line 1
INFO: Error : 1064

what could be wrong?

Answer 1

You’re passing an string representing an invalid SQL statement to the executeUpdate() method when you don’t need to. Try just doing prep.executeUpdate();.
